BAILER FOR OIL AND OTHER WELLS.

SPECIFICATION forming'part of Letters Patent No. 247,753, dated October 4, 1881,

Application filed November 26, 1880. (No model.)

and useful improvement in bailers or instruments for removing fluid, mud, or debris from oil or other wells during the operation of drilling; and we do hereby declare that the following is a full and exact description thereof, reference being bad to the accompanying drawin gs and the letters of reference marked thereon, making a part of this specification.

Figure 1 represents a sectional view of our improved bailer with the valve E raised in position, as when being lifted from the well. Fig. 2 represents a perspective view of our improved bailer with the valve E at rest, as when on the bottom of the well.

The nature of our invention consists in providing the tube of a bailer, substantially as now in use, with a stem-valve adjusted so as to play between two seats-one upright and one inverted-in the lower part of the bailer in such a manner that when the bailer is at rest in the bottom of the well the aperture of the bailer is open so as to admit the fluid, mud, or debris into the body or tube of the bailer, and when being raised the valve is lifted upward against the upper and inverted seat, closing the aperture, and confining the fluid, mud, and debris contained in the bailer while the same is raised to the top of the well.

To enable others skilled in the art to make and use our invention, we will proceed to describe its construction and operation.

We construct the body or tube of the bailer of any convenient size and form, as at A in the accompanying drawings. Near the lower en(l of this tube A, and upon the inside of the same, we make fast the inverted valve-seat B. Below the valve-seat B we make one or more side apertures, G G, into the tube A. 7 Below the apertures O O we fix the valve-seat D. Between the valve-seats B and D we adjust the stem-valve E, to which is attached the stem F at the lower end, the stem extending upward inside the tube A, the upper end protruding above the tube Athrough a hole in the cross-bar G, which is made fast to the top of the tube A to keep the stem F in the center of the tube A. The upper end of the valvestem F we provide with the eye H, through which we attach the line used in working the bailer.

The stem-valve E may be also described as a false or loose bottom to the tube A, as it closes upon the valve-seat B from the lower side, and is made small enough to play freely between the valve-seats B and D.

Below the valve-seat D we plug the bailer with plane, conical. or wedge-shaped plug J, to prevent the mud or dbris from filling in and preventing the valve E from falling upon the valve-seat D, which plug also serves as a spud in the bottom of the well.

Thus constructed the bailer operates as follows: We lower the bailer into the well by means ofa line. As soon as the bailer reaches the bottom of the well it comes to a rest. The valve or false bottom E drops from the inverted seat B to the upright seat D, leaving the apertures G 0 open into the tube A, into which the fluid, mud, and debris enter unobstructed. The bailer being filled, we draw upward on the line, which raises the valve E against the inverted seat B, closing the opening through which the fluid, 8w, entered the bailer, and the bailer and contents are thus raised out of the well. We then swing the bailer to one side of the well and relax the line and let the foot of the bailer rest upon the ground or other substance, whereupon the valve E drops to the seat D, and the contents of the bailer rushes out again at the apertures O O unobstructed.

By means of the stem-valve E, adjusted as herein described, we obtain a jar useful in starting the bailer when it becomes stuck from any cause in the well.

What we claim as ourinvention, and desire to secure by Letters Patent, is-

A bailer provided with apertures O G and valve-seat B, in combinationwith the closed base J, valve E, and valve-stem'F, substantially as shown and described.
